TSB update
UPDATE: TSB Report#A17A0063: F-HPJE, an Airbus 380-800 aircraft operated by Air France, was conducting flight AFR066 from Paris/Charles de Gaulle, France (LFPG) to Los Angeles, CA (KLAX) with 24 crew members and 497 passengers on board. At 1349 UTC while in cruise at FL370, the flight crew declared a MAYDAY when fan and inlet components of the number 4 engine (Engine Alliance GP7270) separated from the engine. The flight crew shut the engine down and diverted to Goose Bay, NL (CYYR) where a landing was carried out without further incident on Runway 26 at 1543 UTC with ARFF standing by. Substantial damage to the number 4 engine inlet section was visible, as well as visible damage to slats and fairings inboard and outboard of the number 4 engine. A runway inspection discovered debris on the arrival runway, which needed to be removed before the runway could be reopened. The Transportation Safety Board (TSB) of Canada, Bureau d'Enquêtes et d'Analyses (BEA) of France, and the National Transportation Safety Board (NTSB) of the USA deployed investigators to CYYR. Advisors from Air France, Airbus and Engine Alliance (specialists from Pratt & Whitney USA and General Electric) also travelled to CYYR to assist. The Flight Data Recorder (FDR) information was used to confirm the area of the engine fan separation to be approximately 150 kilometers southeast of Paamiut, Greenland (territory of Denmark). Danish authorities delegated the investigation to the BEA.
